The Brazilian midfielder was heavily linked with a move to England during the summer before signing for Shaktar Donetsk for just over £20m instead.
The talented 21-year-old has experienced difficulty in making the adjustment to European football and has rarely played his best football under Mircea Lucescu.
And now the former Atletico Mineiro star has admitted that the political situation in Ukraine has given him further reason to question whether he made the right move.
He said: “The demonstrations in the city centre, in front of city hall, have already begun.
“My parents and a cousin live with me. I have already talked to the ambassador of Brazil about if it gets worst if we leave Ukraine as soon as possible.
